AMD processor - doesnt say dual core on the chip - but is it dual core?

[dubcat]

Hi - I recently purchased a second hand CPU from an auction site. The processor was advertised as being from the AMD x2 family and the speed was listed as being 4200+ so therefore should be a 4200+ X2. The picture of the processor in the advert is this:

The CPU I have recieved is different. The top line reads AMD Athlon 64. The X2 is missing. However the next line down (ADA4200DAA5BV) is exactly the same as on the processor I got. I googled this number and got lots of hits back which ALL relate to a 4200+ X2 processor (dual core).

Is the processor I have dual core? If so why would the X2 on the top line be missing?

I hope someone can help - this is the first time I have ever bought anything from EBAY and I'm in a bit of a panic

Dub.

p.s. - the chip is socket 939 - not sure if that is relevant

Yes, that's an X2. ADA4200DAA5BV is the code for an X2 4200 with the 90nm E4 Manchester core.

Oh god - i better write an apology to the seller retracting the email in which i demand a refund. Note to self - never write an email when in a panic mode!

Ok so how come it doesn't say X2 on the top like the one in the piccy? Is that normal?

There isn't such thing as a (single core) 64 4200+ so it has to be an X2.

As for why the X2 is missing who knows.
